Marina is a fifteen-year-old mermaid who lives at the bottom of the sea; alongside her sisters, loving father and dolphin friend she explores sunken ships and gazes at human treasures, all the while longing to see the outside world. In secret, Marina swims to the surface one evening and sees a beautiful prince that she instantly falls in love with – but the evil sea witch uses her powers to sink the prince’s ship, casting him into the cold water below. Marina saves her love but remains hidden while he comes to on the shore, leaving her yearning to see him again. To fulfill her desires Marina visits the sea witch and exchanges her beautiful singing voice for human legs – but there’s a catch. If the prince marries another, the morning after Marina will die of a broken heart and will turn into sea foam...
Both shows are old fairy tail movies about girls who have to break a spell without speaking plus another task. Mermaid has more tragedy to it where Swan keeps things on the light side but if you liked one you should enjoy the other.
One day, on one of his hunting trips, Prince Siegfried sees a band of swans resting peacefully in the lake. One particular swan captures his attention, because it’s wearing a crown and stares at him just like a human. Siegfried is mesmerized and follows the swan all the way to some ruins, where the pretty swan suddenly transforms into a beautiful lady. The beautiful lady turns out to be Princess Odette, who was put under a cruel spell by the evil wizard Rothbart; and it is this spell that makes her turn into a swan every day, regaining her true human form only when the moon shines upon the lake. The only thing that can break the spell is the unconditional love of a man for her, which Siegfried is eager to give, but things aren’t as easy as they seem.
Both shows are about SWANS. Now that that is out of the way they are both quite old and tell a tale of people needing to break a spell that turn them into birds. Both have that fairy tail thing going on while Swan Lake is about a girl swan The Wild Swans are about boy swans. You'll enjoy one if you liked the other for sure. SWAN!
